LET'S SEE, THE BILL OF RIGHTS? UHHH, IT SOUNDS FAMILIAR . . .

Caroline Kennedy says that when she took a class at New York's Columbia Law School on civil rights, she wasn't quite sure what the Bill of Rights was.

"I'd heard of it, but I don't think I knew it was the first 10 amendments to the Constitution," Kennedy, 33, told People magazine in its Feb. 11 issue.That class inspired Kennedy, and schoolmate Ellen Alderman, 32, to write a book called "In Our Defense: The Bill of Rights in Action." The women took turns writing up each case, then edited each other's work.

The book is a collection of court cases illustrating the Bill of Rights, which was ratified in 1791. The book, to be published this month, celebrates the Bill of Rights' 200th anniversary.
